No cellular network after installing CM12.1 on Straight Talk SM-G900F (klte)

I recently installed TWRP and then the latest snapshot of CM12.1 for my phone described in title. The android version was upgraded from KitKat (4.4 I believe) to 5.1.1. Everything works fine with the install except I have no network whatsoever. Can't text, can't call, can't use data etc. I made a post on the CM subreddit but didnt get a lot of help (can't post link) . Here is what I have tried: changing APN settings (which I have heard should at least let me call and text if incorrect); flashing various modems such as BOE3, BNL9, and BOD3 (all of them get a FAIL! (auth) in ODIN); restoring my KitKat backup (makes the phone unusable); trying to flash the default L rom for the phone (Also fail to flash in ODIN and TWRP). So at the current time I am basically stuck on CM12.1 and all of its amazingness with no phone functions, I basically have a small tablet at the moment lol.
Here is some information from the about of my phone, if it is helpful at all.
Model: SM-G900F
CM Version: 12.1-20151204-NIGHTLY-ktle (Installed the nightly after the snapshot didn't work, same problem persists)
Android version: 5.1.1
Baseband version: S902LUDU3AOG2
Carrier: Straight Talk
If any more info is needed, just let me know. I appreciate any help, as I am pretty much at square one still. I have googled for days to try to fix this, and haven't come up with anything. It seems no one has had this specific problem before.
If I can't fix this issue, is there any way I can downgrade back to what I had to begin with?

y tried with another sim card !!!
ty *#06# to verify imei

I only have one other sim card on me, and its through verizon. It didn't work on the phone either. I would definitely just buy a new sim card if that would mean it would work. The whole IMEI thing worked, but I am not sure what to do with that information.

(Definitely a G900F? Check what it says in download mode)
Checking the IMEI was to make sure you haven't wiped/corrupted the EFS partition, which contains the Radios needed to make and receive called, along with the IMEI (Hopefully you researched enough to back that up before messing with the phone)
Try flashing another stock ROM with ODIN 3.10.7, go for a different Lollipop ROM from sammobile. com
Some stock ROMs fail to flash, some work, (Phone dependant it seems)
Then boot into recovery and factory reset > try to boot

I have tried 2 separate L roms for the G900F. It says in download mode the phone is a SM-S902L and I read somewhere to get the true model of the phone you look at the FCC id under the battery. Well the FCC id says it is a G900V. at one point in trying to fix it, I tried a stock L rom for the G900V and TWRP told me that it was intended for a kltevzw device and that mine is a klte, so that is why I assume that it is in fact a G900F. I have been using ODIN 3.10.7 to flash everything as well. (Have't tried TWRP for the most recent tries since it takes longer to setup and I doubt it would work but it's worth a try I suppose.
I looked on Sam Mobile for the SM-S902L and there is only one firmware for it, which is 4.4.2, the same one it was installed with when I got it. From my understanding SM-902L is the straight talk branding of the G900V, and trying to flash that firmware didn't work either. Every time I try to flash something it terminates with a FAIL! (auth). What I also understand is that Straight Talk has not released an official version of L for the phone. So it seems my options now are to somehow get the modem to work right in CM12, try to somehow downgrade to 4.4.2, or wait for Straight Talk to release an update for my phone which is not really an option. I just got this phone and I really don't want to have to buy a whole new one just because of software problems. In my mind there HAS to be some way to fix this.
EDIT: my bad, I should have mentioned when I tried to flash the G900V rom it was also CM12, not a stock.
EDIT AGAIN: I seem to have fixed this problem. I have no idea how I did it, but I finally got it to restore to the stock 4.4.2 rom. I seriously have no clue how it worked but it did. Texting and data once again work, but i am now having a problem where I can't make or receive calls. Call immediately ends/goes straight to voicemail. I don't suppose you know anything about that, if you do that would be awesome. I'm gonna call ST in the morning and see if they can tell me anything from their end. But otherwise, I guess my problem is solved. Lol.

I know it sounds simple or may sound stupid but have you tried entering your APN? I have to do that with most of the custom Roms I flash or I won't have service. Also, make sure the correct modem is flashed and up to date.

Bricked AT&T GALAXY S6 EDGE PLUS

I was trying to root my at&t s6 edge+ using Odin. As soon as the process completed, my phone froze on Samsung screen. Then I tried wiping cache and data but nothing worked. I downloaded few stock ROM for Odin but flashing keeps on failing. I read in some thread that new Samsung devices do not support downgrading. I went and checked my current build number and found that to be G928AUCS4CPK1. However, the firmware I was trying to flash were older version.
Has anyone experienced similar issue before? The main problem here is I cannot find the exact build number anywhere. I spent a lot of time searching and finally decided to post here.
Your valuable suggestions will be greatly appreciated.
Thanks.

hey man, you flashed an older version of the firmware? even if it wasnt bricked, your phone is essentially useless now. the efs is gone, meaning you cant make phonecalls or connect to wifi at all. sorry; your phone is bricked. perm.

download mode dosen`t work ?if so the only thing you can try is to use samsung kies to restore your phone but don`t know if that works

I done something similar to my standard S6 Edge the only difference was i was able to start it up ok and i thought everything was ok until i realised i had no reception. I so happened to notice my imei number was gone. I had no back ups of the partition that saved this info so i totally bricked my phone.
I did however find a website that would be able to do a work around ( for a fee of course) for it however it does question your morals as its essentially illegal in alot of countries. I dont want to post anything on here so if you want any info send me a PM.

Exact same thing happened to me... went to AT&T repair center but they didn't have the 'K1' firmware..
anyhow managed to find the latest firmware (gsm-firmware.com)... cost me $4, but the phone is up and running... I only flashed the AP file.. also used Odin 3.12.5..

Need EFS/IMEI help - I have backup but still not working

The Story
Don't even know where to start. Okay so I have a SM-935W8 (Canadian Version) and it was working perfectly fine running Project Dream rom the S8 one. I decided to flash angelo's Pixel rom for S7 Edge and for some reason when it booted, the network had a cancel sign meaning no network. Once I finished the initial setup, calling, messaging , and data weren't working. Luckily I have a backup for EFS and RADIO in tar, img. and tar.gz formats. So I downloaded the Partitions Backup app and restored the EFS and Radio files, it said successfully restored. I rebooted my device and the issue was still there, no network. So then I installed the stock ROGERS (Provider) rom from SAM MOBILE and it came up with some DRK error and my phone would not boot. So then I quickly used ODIN to flash twrp and then flash Superman Rom (Love it) and use dm-verity bypass.zip to get past the drk error. Then I attempted many other things but to no avail such as flashing the EFS tar through ODIN which caused a "Software Error" and phone to be stuck on a light blue software error screen so I had to use smart switch to FULLY restore the phone back to booting up, then once again I flashed twrp and Superman rom with dm-verity so I atleast have root and a decent rom to work from.
The Problem and What I Have at Disposal
So essentially, I currently have a new section in settings under Connections called "SIM card manager" for managing sim cards even tho I only have 1 slot, it shows that the SIM is ROGERS and LTE/3G/2G in there, but it can't connect to a network and keeps saying Not Registered on a Network. Also, there are 2 IMEI's since my phone thinks theres 2 SIM slots but I really only have 1 slot. BUT HERE IS THE MAIN ISSUE, THE ROOT OF ALL PROBLEMS, the IMEI is reading as "000000000000000" and the IMEISV is "01". Hence im getting Not Registered on a Network. No secret codes such as *#06# are working, keeps giving the Not Registered on a Network error.
I have the EFS and RADIO backups in img, tar, and tar.gz formats as well as screenshots of all my MAC and Bluetooth addresses, IMEI and Serial #'s and all that information. So essentially I feel fully ready to solve the problem but everything I try keeps failing. My EFS restoration says successful in the APP but upon reboot, theres no change. Flashing the EFS through ODIN messes up phone harder. When I use EFS Professional Tool, where do I place the partitions so they show up in the tool?
I used this post to try to fix it: https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516
BUT when I'm flashing the combination through ODIN in AP, it goes to NAND write or whatever and gets stuck, sometimes it gets stuck on Analyzing files or something. I tried every single ODIN version. I really could use some expertise on this issue. A step by step written tutorial, some method anything!!!! Help on this post or even teamviewer or skype for live help would be appreciated. Please help and I'm willing to compensate for successfully helping me fix my issue..

Did you ever sort this out? I'm in a similar situation, except that it does occasionally show my IMEI but also 'baseband unknown'. But still no network access.

i hope i dont risk a warning, but you can use xposed and with root you can change your imei and baseband info.

Thanks, I've done so much to this phone now...
I did try xposed and have tried a different IMEI, it seems like it's a modem issue but there doesn't seem to be a firmware solution - I have tried so many stock roms(All the way back to the first Marshmallow and a bunch in between) and different custom roms too but in the end the error is always there: Not registered to Network.
I saw somewhere in my troubleshooting that some kind of cert needs to be patched because the phone did an update on a modified rom without the OEM unlock being on and then the EFS data was messed up or something like that (all of the research and troubleshooting is starting to blur). It seems like that fix isn't doable without a rather expensive piece of hardware (expensive if your just fixing your one phone I guess) and there isn't any firmware-only fix that can accomplish this patch so I'm stuck again.

Sorry, I should have clarified. I have an S7 (SM-G930W8). I only tried this thread because the issue was identical to mine and I couldn't find anything similar referencing the S7 specifically.

For anyone coming across this thread in the future, although mine was an S7 I think the issue would apply to both. I ended up ordering a z3x in order to use the patch certificate. But it wasn't that easy; the firmware had to be downgraded to marshmallow first which wouldn't work in Odin until I tried just flashing the BL and CP files first, then rebooting and flashing the AP and CSC files separately. In fact, the AP file froze the first time but passed on the second attempt. After that, everything was downgraded to android 6 and then the patch certificate option worked and my s7 connects to the network again.

I'm having a similar problem with my sm-g935w8 Rodgers but has been unlocked. A couple days ago i looked at my phone and it was showing a no signal symbol and I look for my phones information and it showed unknown in all categories, the imei say unknown, and it's not reading the sim. Help me

Help me with flashing stock firmware

Hi
I got my wife a Samsung S8, SIM free as it was cheaper to buy the phone out right and get a 3 SIM only deal.
Only problem is because we got the phone from a online retailer, 3 won't activate the wifi calling.
So I have decided to flash the 3 S8 firmware via odin to my wife's phone but before I do that I have a few questions so I know I don't mess things up.
I will list the questions in number form so could you list the answers in number form with answer matching the question number, so I know what people are talking about.
1. When I glanced at Sammobile, I saw nothing mentioned about 3. Only thing I saw was H3G does this mean 3....if not what is 3 software listed as.
2. Will flashing this firmware wipe or factory reset her phone. (I know that I need to back things up anyway)
3. Will doing this Firmware flash void her insurance. As it's official Samsung software, I didn't think so but I want to be sure.
4. After the update will her phone be locked to 3.
5. Has anyone got any tips and guides which can help with this.
6. I hear that you can google blocked doing this type of thing, how do you get around getting blocked and if I do, how do I unblock a google blocked phones.
7. Will flashing 3 firmware actually give me wifi calling in the end.
8. After I have installed the firmware....will I receive future android/ Samsung updates. E.g. android 7 to android 8 updates, security patches and bug fixes
Thanks guys I will leave those questions for now....if I have anymore I will add them on another comment.
Hope you can help me I have attached some stuff I saw on the net incase it helps in anyway

Firstly, there are Dozens and dozens of flash guides all over the web on flashing a SS phones with ODIN, 2nd'ly, its one of the easiest phones to flash..
Before you do anything download and install the latest SS USB drivers.. plug your phone in so they are detected.. then goto>settings and turn ON USB debugging in developer options.. plug in phone again.. so the device is detected again, then unplug... this installs the (A)ndroid (D) ebug (B)ridge driver, leave USB Debugging ON..
Your questions:,,
1) Yes H3G is 3UK... also EE use wifi calling..
2) Yes, it will wipe her phone... When you download your H3G firmware.. there are 2 CSC files in the folder.. I recommend using CSC... do not use HOME_CSC
3) No it will not void the warranty... its only when you trip KNOX by rooting, or custom roms that you invalidate warranty... Stock is fine
4) Yes it will... you will have to get an Unlock code to SIM unlock her phone.. SIM Unlock.. is not Flashing a rom.. What makes SS devices so cool.. is that you can flash any stock rom from any provider.. and it doesnt affect the bootloader, so you could flash an unbranded (open), EE or O2 rom on your 3 SIM locked phone..
5) Theres so many on the web and on XDA for SS phones and ODIN flashing, just type "Galaxy S8 back to stock" into search. My advice.. READ READ and more READ the guides ALL THE WAY Through, before you do ANYTHING AT ALL.. and make sure the phone you have has no SIM locks or security locks on it before you start.
6) Never heard of this... its only a stock rom your flashing, youll be fine
7) If 3 support Wifi Calling and the Rom your flashing has it coded in, then Yes it should work fine. EE also support Wifi calling
8) Yes... its a STOCK Rom with a STock recovery and STOCK Knox... so you will recieve updates according to when they are rolled out by that prvider... So, if its a 3 Rom, youll get updates when 3 push them out... if its an O2 rom, youll get them from O2.. and so on.... That is why soo many people flash Unbranded/Unlocked Open Roms... because unlocked phones have, in the past, gotten updates first and factory unlocked phones / roms dont come with Bloatware / carrier rubbish apps installed ..
Remember.. Just READ everything
Hope this helps

Thank you so much. I will make sure to do my research. I have used odin before so I have some experience using the tool but not for big things like this. Last thing I used it for was to download TWRP to my rooted tablet.
I will also pull out her memory card so she can save her photo......she will be pissed about the wiping the phone part but if we want wifi calling then needs are a must.
Anyway of backing up her phone on a level where I can just put in her user name and password it will literally restore back to the point of the last back up....eg install all her the apps and themes the way she had them before the firmware update.
It's really important I nail this, as this is the first time we have gone SIM free and I don't want to be going back to paying extra for contracts just because we need the wifi calling. (And we both hate the three in touch app)....so my success with this will be important for the next phones we buy.

Hi....i seem of got myself in a pickle.
I read countless amounts of guides and watch loads of videos but still not gone right. (Phone isn't broken thankfully)
Basically I do everything guides tell me, but it's when I press start on odin the problem happens. It doesn't fail but it doesn't progress....on the text box it stops at a point that says Nand START (something like that) but doesn't get past that point....i sat for an hour the first time I tried it and 30 mins every time after that. Another thing it does is at the top where you get the green loading bar....that part goes white and says something like select Partition (not near my pc at the mo and when I was with the pc my wife had my phone, so couldn't take a photo)
I have 3 solutions that could be causing the problem but I just want to get a second opinion.
1. I read everywhere about device drivers and I was under the impression that they downloaded automatically when I plugged the phone to the pc....is there secondary drivers I need to download (sorry for the basic question)
2. My odin wasn't the latest version....i was using odin 3.09 and now there is odin 3.13 (I think) will using the latest version stop this problem.
3. I wonder if my antivirus is blocking it....do antivirus's ever get in the way of flashing firmware.
Hope some can help before tonight

Hi again everyone.
I feel like I am talking to myself here. I have managed to sort it.
I downloaded some secondary device drivers for her phone and then update odin to, Odin v3.12.7 and it worked first time.
I also used the original charging cable instead of the official charging cable for the gear 360 camera.
To restore her data, I backed up to samsung cloud in the settings, signed her in and restored the date I backed up....didn't originally think it would be any good but I am impressed.
Result is I have a phone that has wifi calling and I read somewhere that if you take the SIM out of your phone when you download the firmware it doesn't SIM lock the phone.....and it seems to have worked. (Not sure how true it is or if I was just lucky)
Hope this thread helps, I want to cover a few different things in it and learn something on the way.
(Thanks to the person that commented and supplied most of the info in this thread)

Hi everyone.......again.
My last post I promise.
I wrote a bit of a guide for myself for when I need to do this again. I thought would post it here so people can see it and use it if they wish.
(The notes before the method is apart of my guide. Hope it all helps)
Notes Before The Method
the cable you are using to connect to the pc should be the original charging cable. (If you don't have the original then use the one your using and see if it works but try to find a official Samsung charging cable)
Your phone needs to be at least at 60% battery.
Older phones sometimes don't work with newer versions of Odin so if this is happening download a older version.
If it's a new phone and you want to personalize it from scratch then no need to back up and restore any data.
After removing your memory card, plug it into your computer using a memory card extension and copy photos to your computer. Just in case the phone formats the memory card when entered back in to the phone, after the firmware is installed.
Method
1. Go to Sammobile via Google chrome in incognito mode. (If you don't do this they will re-direct you to a sign up page, everytime you press download)
2. Download Firmware, find this by picking the lastest firmware thats with your network and match the Baseband version or the last part of build number. (found in system info in the settings)
3. Install the latest version of Odin and install secondary device drivers on your pc/Laptop.
4. (On your mobile) back up your data in the samsung cloud.
Setting>Cloud and Accounts>Samsung Cloud>Backup settings> Back up.
If you have a memory card, move all your photos ect, to it and remove it from your phone.
5. Go into setting and tap build number 7 times to unlock developer options. After unlocking it, enter developer options and enable usb debugging.
Setting>developer options>USB Debugging.
6. Once the firmware file has stopped downloading on your pc extract it and send send it to your Downloads File.
7. Open Odin and load each part of firmware in the right box e.g. AP with AP, BL with BL, CSC with CSC ect (Do not load up Home CSC this is used for when your moving a branded device to another brand, E.g. EE to 3)
8. Before you plug your phone up to the computer. Turn your phone off and enter Odin mode(Download mode). Each device has a different way of doing this so just google how to do it on your specific device.
9. Once your phone is in download mode plug it into the computer and press start. This should take a few minutes but some files may take longer.
10. Once the Odin confirms the process is done, by showing the pass sign unplug your phone and turn it on. (First time you turn it on May take a minute or two to load. )
11. Enter your google email and password, and restore all your data on google.
12. Then enter your Samsung user and password, after that press restore and choose the date you backed up on before you flashed your phone (at point 4)
13. Enjoy....your all done.

Note 4 N910C Emergency Call only (Not Registered to Network) IMEICERT:PASS (IMEI Ok )

Greetings Folks
I have a N910C and as mentioned in title recently I got stuck in to this issue
How it happened
I had CF-Rooted my phone and Odin flashed TWRP for custom ROMS so I tried a few and was not getting the perfomance thought SimplROM would do it for me in order to install that ROM it said in instructions to install latest Modem and Bootloader
So i tried downloading the ones given in v6C BL was downloaded but CP kept on giving me errors getting stuck at 7% on mega so being stupid I downloaded DPCB(MODEM) While ROM was offering DPK4
So everything went fine until after boot I realized am facing Not Registered to Network
Since I had experienced this before on other phone I went ASAP in dialer to check my IMEI & SN both are still intact
I knew about EFS unfortunately I backed it up on Phone Storage which was wiped for ROM and I forgot (So dont have EFS Backup )
I do recall years ago back when I had S3 I experienced this and sometimes flashing different firmware(CSC ,Modem) fixed it
What I have tried so far
I have already tried several stock ROMs most of em had DPI1 Baseband except 2 other ROMS no luck
tried combination file method too (the one that helps downgrade to kitkat i believe ) no luck
Tried XEO repair Firmware no luck
any suggestions ??
and on that contrary now that I am not on stock is there any way to find out which CSC and Stock ROM this phone originally was one or came with with IMEI or Serial I believe ?
Thanks in Advance

Anyone??

under the battery there's the serial number
install on your pc samsung smart switch program
run it with option of emergency software recovery - device initialisation
input the model of your phone
input the serial number
start
have patience and a good connection
your phone will (eventually) get the latest official firmware

at least you'll have a working phone with stock rom
from here on you can try again and get informed better on what to do
good luck

Hey there bud I have almost tried most of fixes I could I'll give Smart Switch a try as I recall I checked before it didn't have initialization just the recovery mode, while in Kies 3 I did try initialization method by model and SN but it prompted device doesn't support initialization
Anyways do you think it could fix network?

Maybe restore the efs from recovery, if you have a backup that was working.

Yep. Same problem as mine. Im kinda lost now since i dont have anything; even in stock rom it cannot go beyond connecting to my carrier. It only able to read my contact.
Im guessing its a motherboard problem? Isnt it @w41ru5?

I don't know. Usually it's a modem issue when not recognizing the sim.
If it's a 910F snapdragon it might be the infamous eMMC issue.
If you have an EFS backup try to restore it from recovery TWRP.

Assuming its modem problem, its related to motherboard i guess, right?
Finally got the phone working, only to discovered that SIM not working. Really wasting my time and hype!
Plus, its hard to search for n910c replacement board here.

The firmware, not the physical one.
Did you try to flash the 4 files repair firmware?
This is an example, I don't know what phone you have
https://firmware.gem-flash.com/index.php?a=downloads&b=folder&id=7081
Did you try the SmartSwitch pc program?

"...4 file repair..."- what? Ive google it until im almost run out of data here and you have a possible solution? You must be active in note4 forum.
One thing i noticed that, the IMEI and Serial Number are different from the sticker included.
I will try it, but not immediately; waiting for thurday-friday for data renewal.
My phone is n910c
EDIT : just checked the page you gave. I have few question;
What should i do with the files? What are the step? What are the program needed?
Is it related to SmartSwitch as you mention; need to use it?
Thanks!

1. It's good you still have the IMEI. Not so important if they're different from the sticker. Where did you buy the phone from?
2. So if you go to check the 4 files repair, you need to search on that site the files for a 910C.
3. Did the phone worked on your country provider? If yes, maybe you need to search for the 4files corresponding to your region code.
4. These 4files have to be flashed with Odin

5. SmartSwitch is an alternative to get the latest firmware for your phone according with the model and serial number.

the "firmware.gem" are useless. the error says i need another package (i assume a quota) to download the needed files.
im currently testing "zfirmware", but have a doubt since it only give 1 type file (which country is it i dunno). but yeah, since my phone like that, it wouldnt hurt to try
EDIT : yep, nothing changed. the device not even bricked.

If something does not work, why do you give up so easy?
http://www.mediafire.com/file/a2fdo0xm9nat5jt/N910CXXS2DPJ3_N910CZTO2DPE2_ZTO.zip - this is marshmallow
https://androidfilehost.com/?fid=24269982087001472 - this is for lolipop
Put the phone in download mode, open Odin and try.
And try the smartswitch also.

I tried files from LP and MM. It didnt work. And also smartswitch.
I was hoping that it will brick the phone (if i ever missed a step or incorrect file) but it didnt.
Might as well try looking for replacement board (or even a refurbished note4).
Thanks though for the suggestion @w41ru5!

Greetings again folks reading your replies above I have been trying almost every fix there is out there
First of all about Emergency Calls Only/Not Registered on Network
It can be due to several causes its can be Hardware ie faulty modem
it can be bad network coverage
it can be bad simcard
it can be SW with EFS problems or maybe even on rare occasion a modem file that you flashed
EFS can be either bad IMEI with CERT : FAIL or Just Network with IMEI and SN intact
just dial *#0011*# and see if you have CERT : PASS ( also someone with good IMEI/CERT and working network can share screenshot so i can compare whats wrong)
I am certain mine is EFS related because it happened after flashing modem DPCB modem via ODIN (I had TWRP EFS backup but the blunder I made was backing it up on phone storage and being careless forgot it was there and was wiped for custom ROM flashing process)
So far what I have tried
Combination File Method (and even downgrade to KK 4.4.4 )
Repair Firmware that include AP,BL,CP,CSC and even PIT
Kies 3 or Older Smart Switch says (Device doesn't support initialization ) since initialization feature was removed by Samsung on newer Smartswitch(since it was being used for wrong reasons? read somewhere)
Several different firmware's
OTA update
My IMEI CERT says PASS if only we had a network patch like Ariza Patch (for Galaxy S3) for Note 4 then we would be in luck so far at this point I dont think flashing ROM's would even help with bad EFS our only luck is Box e.g Z3x or Octo dont know if we are allowed to talk about those here (ill edit post if not)
these box applications have Network Patch for most Samsung models but I don't see one for N910C in most versions
for those with bad IMEI they can try writing good cert or efs on note 4 since they have already lost it I am sitting on it because my EFS is good on that part and for some reason box app isnt allowing me to back up my CERT if I am able to back up current cert then ill give those a try but I would prefer current IMEI since in my country IMEI should be verified to use the phone or you have to pay tax
I know its Bad EFS for sure because using Box application I chose reset EFS(after backing up current faulty EFS with good IMEI) upon reboot phone's imei was changed with no SN network came back for few seconds then gone again ,this happened to many users that have tried resetting EFS so I restored my original EFS
if anyone here with N910C and root can give me EFS folder I can corelate if any file required for network is missing since i have good IMEI
Cheers!
